The dashboard hardware is broken, need to exchange some chip to fix.

Thanks, that's also what I am thinking. Just don't know which chips are faulty.

Is there a single chip that's responsible for controlling all the LED's? It seems more than one LED's are affected now.

I think maybe ledcontrol broken or breakdown. Maybe you can find a chip which a lot led connect to, and exchange it.

I know some people can repair it in China, it coast 60USD above.
